Digital Dimming Data Input [Function Mode: 4]

• MSM9210 receives the digital dimming data when function mode 4 is selected.

• The output duty changes in the range of 0/1024 (0%) to 1016/1024 (99.2%) for each grid.

• The 10-bit digital dimming data is input from LSB.

Master Mode

Master Mode is selected when M/S pin is set at High level. The master mode operation is as

follows:

• The input levels of DIM IN, SYNC IN1 and SYNC IN2 are ignored, and these pins should be

connected to L-GND or VDD.

• The pulse width of GRID1 to 3 and SEG1 to 32 are controlled by the internal digital dimming

circuit.

• The segment Latch1 to 3 corresponding to GRID1 to 3 are selected by the internal timing

generator.
